At Skypanels, we offer different sizes and styles of decorative light diffusers. For example, the classic Skypanel fluorescent light diffuser is perfect for a hospital, medical or dental building or virtually any other office setting which uses fluorescent lighting. Classic Skypanels are designed to fit all standard size (23.75" X 47.75") fluorescent light housing fixtures. Do you have a non-standard fluorescent light housing fixture and unsure if our panels will fit your custom fixture? Choose the "CUSTOM SIZING" feature and we will custom fit your Skypanel design to fit perfectly in your lighting fixture!
